China’s Fifth Plenum: Xi’s Party Discipline Meeting Explained
China fifth plenum: the Central Committee meets Oct. 26-29 on party discipline. How plenums finalize purges and what to watch next.
China’s Communist Party leadership opened a four-day closed-door meeting in Beijing on Monday, Oct. 26, 2026. The fifth plenary session, or plenum, of the party’s 20th Central Committee is scheduled to run through Oct. 29, and its official theme is party discipline. This China fifth plenum explainer covers what a plenum is, what is on this one’s agenda, and why it matters for China’s military and for the 2027 party congress.
What a plenum is
The Central Committee is the Communist Party’s apex institution, with 205 full members and Xi Jinping as its “core,” according to the Congressional Research Service (CRS In Focus IF12505, updated April 27, 2026). It meets in a plenum at least once a year. A 23-member Politburo and a seven-member Politburo Standing Committee, China’s top decision-making body, sit inside it.
Reuters, in a factbox published Oct. 23, describes how the meeting works: roughly 300 full and alternate members gather, attendees are traditionally confined to the venue, foreign media get no access, and the state news agency Xinhua usually issues a summary on the closing day, with a more detailed document several days later.
What is on the agenda
State media say the meeting is about discipline, not economics. According to a Xinhua report republished by China’s government portal, Xi delivered a work report on behalf of the Politburo on Monday and explained a draft decision “on some major issues concerning strengthening full and rigorous Party self-governance with perseverance.” Xinhua said the draft “sets out strategic plans” for party building “at present and for some time to come.”
Reuters reported that personnel deliberations, and decisions on disgraced former officials, are also likely to feature prominently.
Why plenums matter for purges
A plenum is the step that finalizes the fall of senior officials. The Pentagon’s 2025 China Military Power Report explains that disciplinary cases against Central Committee members “apparently need to be reviewed at a Central Committee plenum,” and that formal prosecution can proceed only after that. As an example, it cites two former PLA Rocket Force leaders who were detained in summer 2023 but not expelled from the party until the Third Plenum in July 2024. Brookings Institution scholars add that only a plenum can make personnel changes to the party’s Central Military Commission (CMC).
The backlog is large. CRS reports that since the 2022 party congress the Central Committee has lost 14 members (12 expelled, one resigned, one died), the Politburo has lost one member to expulsion, and the CMC has lost three members to expulsion. A separate CRS brief on the People’s Liberation Army (IF11719, updated July 22, 2026) says Xi appears to have removed or sidelined more than 100 senior officers since 2022, and that the CMC, which had 11 members when Xi came to power, “now has one sitting member aside from Xi.”

Why it matters
Analysis: Peter’s World interpretation based on the sources cited above.
A plenum devoted entirely to discipline is unusual. Most recent sessions paired personnel moves with a major policy document, such as the economic plan reviewed a year ago. Making discipline itself the headline suggests that the anti-corruption campaign, now in its second decade, is being turned into a lasting set of rules rather than wound down.
The military dimension stands out. The CRS figures describe a high command reduced to its thinnest level in Xi’s tenure, and the Pentagon links a plenum vote to the point at which a case can move to prosecution. That makes this week the most likely moment for formal decisions on officers who have disappeared from view. The Pentagon judges that the purges “very likely risk short term disruptions” to PLA effectiveness, even as it says they could improve readiness over time, which is why outside analysts will read the closing communique for military names.
The meeting also opens the run-up to the 2027 congress. CRS notes Xi has not said whether he will seek a fourth term as party leader. Whatever this plenum decides about discipline and personnel will shape who is eligible for promotion next year.
What to watch
